Y lie it lcnown that I, \Vrnnuw G. Evs'ron. citizen of the'United States, residing at St. Louis. State of Missouri, have invented cer-. tain new and useful Improvements in Resuscitatiug Apparatus, of which the following is a full. clear, and exact description, reference being had .to the accompanying drawings, forming a part hereof. My invention has relation to improvements in resuscitating apparatus; and it consists in the novel features of construction more fully set forth in the specification and poiuted'out in the claims.

in the drawings, Figure 1 is a top plan of the apparatus, with parts broken away; Fig. 2 is a' side elevation showing the receptacle perfectly balanced and set for opera- .tion; Fig. 3 is a horizontal section on the line 3-3 of Fig. 2; Fig. 4: is'an end elevation of Fig. 2; Fig. 5. is an end elevation showing'the receptacle unbalanced or out of equilibrium; Fig. 6 is an enlarged elevational view of the spring-controlled triggervalve and portion of the stationary frame cooperating therewith and with thereceptacle or body-receiving casket; Fig. 7 is a horizontal sectional detail on the line 7.7 of Fig. 0; Fig. 8 is a vertical sectional detail on the line 8 8 of Fig. 6; Fig. 9 is an inner face view of the upper end of the guide-standard which cooperates with the trigger-valve carried by the tilting recepta lo; and Fig. 10 is an enlarged crosssection on the broken line 10--10 of Fig. 1.

The principle of operation of the present app'araths depends on the fact that an apparently lifeless body deposited in a rece'ptacle or chamber from which the air is partially (or wholly)-.exhausted, will respond to the unnatural environment thus pheric. air into the receptacle,

produced, in the form of an involuntary muscular n'ioveme'nt, such movement suggesting (if not indicating) the presence of life in such body. In one form of my inventionsuch muscular movementis availed of to operate a valve (normally closed) so. as to instantly admit an inrush of atmos= lthereby re- 0 storing not only the properquantity. of

oxygen necessary muse "embo inient of my invention the-restora to sustain life, st-roying the part-ial vaeuum or rarefaction witl in the receptacle-which produced" the %lar movement referred to. In such tion of the normal conditions of pressure but deand air within the receptacle is effected automatically, though the invention broadly contemplates such restoration either auton'i'atically or by the hand of the attendantobserving such muscular movement, and itis therefore the object of my invent-ion to provide an apparatus in which the process of air abstraction orrarefaction and subsequent restoration of the full complement. of air may be carried on in a most convenient manner.

In detail the .invention may be described as follows :-Referring to the drawings, 13 representsa suitable supporting'frame or T and having terminal legs (Fig. 3), the front leg having an upper extension or standard 1, and the side legs having upper extensions 2, the terminals of said extensions being preferably solid, and square in cross-section (Figs. 2, 5, 6, 8). The tops of the extensions 2 are provided with V- shaped bearings. for the support of the knife-edge trunnions 3 disposed'on the sides ceptacle B, one of-the side walls of the latter being provided with a rail 4: along which are adapted to be shifted a series of counterpoise or balance weights w on the order of a scale-beam, the ob ect of the weights being to accurately balance the receptacle B after the apparently lifeless body of a human (or other) being has been deposited therein for purposes of resuscitation. The suspension trunnions 3 are in the middle of the receptacle and the latter when empty 'balances perfectly; but'after a body is deposited therein, (the trunk being as a rule heavier than the limbs) suitable adj nstment. by sliding the weights w along the rail 4 must be made to restore equilibrium to the receptacle.

Mounted to reciprocate in straps or bearing 5, 5, on the front end wall of the receptacle R, is a stem or trigger (5 one end of which (that adjacent the standard 1) is -forked and carries an anti-friction roller '7, the opposite being provided with a disk gate- :valve 8 adapted to cover and uncover a port formed by the hollow bushing or screw-ring 9 secured to the receptacle wall in the path of reciprocation of the stem 6. The latter standard 1 by the expanding action of a compression spring 10 coiled about. the stem .and interposed between the outer strap!) and basecomposed of piping 1n the form of of the tilting body-receiving casket or re-' is normally forced into engagement with the 55 .1 herein as various constructions of lid and joints mi ht be adopted b the'slnlled meventional pressure or vacuum-gagea suitable distance below which the standard 1 has formed therein, and in the path of reciprocation (oscillation) of the roller 7, a notch or groove 13 for the reception of the roller when'the latter has passed off the-- side or edge of the standard with any downward tilt of the receptacle R. The end wall of 'the latter is provided with'anti-friction rollers 7 carried by brackets 14:, the rollers engaging the opposite sides of the standard 1. The receptacle is provided with an conand - with-a suitable nipple n' (with usual checkequipped with a rub receptacle valve asunderstood in the art) for the attaching of a hose l2. leading from any convenient form of exhauster or vacuumpump P.

The receptacleis rovidcd with a'lid L her gasket or packing 15 adapted to engagethe upper edgesof the dow 16 hel by a frame 17 to the lid being placed in proper position to view'the body eposited in the receptacle. The lid hinged to the receptacle, and preferably by 'hinges com osed of a leaf m secured to the lid, the lea being hinged to a screw-bolt m" passed loosely through a bearin 18 on the side wall of the receptacle, an provided with wing-nuts'19, 19, on opposite sides -of the bearing (Figs. 4, 5). The 0 posite wall of the receptacle is equipped with latch bolts 20 which may be swung into recesses or notches'r, the tightening nuts 21 on the bolts coming over the notches whereby the driving home of the nuts clamps down the lid. To-sec ire an even draft on the lid when clam ing the same down, the lower nut 19 may turned so as to pull down on thebolt m (the upper nut being loosened temporarily the necessary degree as per dotted osition in Figs-4, 5) at e same time that he nuts 21 are being driven home. These mechanical expedients however, are not claimed ehanic. he lid is provi ed. with toothed swinging pro s 22, t e notches between the teeth being a apted to en age a pin 23 on the receptacle wall, and t us hold the lid open to any desired degree while depositing .the body of the person to beresuscitated into the receptacle. The latter is further provided with flexed springs 24 which engage 'side against aplugfor'bearin of'-t e ong pipe 0 thesupporting frame B, but; which, with the tilting of Fig. 10), a glass plate or win-- will. now be held down notby the latch the bottoms of the evei'haiigin g portions of the lid, and. raise thesame to admit-air into the receptacle-after the unfastening of the latch-bolts, as will be more fully .subsequently explained.=

R is providedwith a pendent or-swin ing leg 25, which, for a balanced position 0 the receptacle R, 'or when the receptacle hastilted downwardl at that end, bears withits 26 screwed into the end The rear bottom corner of the'rec'eptacle.

the receptacle in, the, opposite direction swings vertically into engagement with said bearing 26, thus serving as a-prop for the receptacle, and holding the same against a possible return to its osition' of equilibrium,

all as will be more fu yj apparent from a-de scription of the operation of the'inv'ention,

which is substantlally as follows i The apparently lifelessperson is deposited in the receptacle R, the lid L ia-clamped down as described, and the weights w are manipulated along 'the rail or beam 4 until' the receptacle is erfectly" balanced. While the receptacle'is eing balanced or rather to permit of the balancing thereof), the attendant first draws the stem or trigger 6so as to bring the valve Bthereof opposite the port in the hollow' ring 9, byseizingthe handle-bar 11. and compressingthe spring 10 until the depression a. comes opposite the" set-screw 12, whereu on by drivin home the screw the stem wlll be held in the position referred to. The valve 8 being set to closed position, brings the roller .7 opposite the edge of the standard 1, so that with any oscillation-of'the receptacle, the roller: will play along the standard. The are of oscillation for the length of sweep accordedthe roller in practice is soslight, that it is rac-' tically a straight line, the full'sweep eing confined between the terminal bevel face '1) and the recess 13. WVhen the receptacle is balanced, the roller-7 bears against the ed e of the standard 1 at a point substantialiy midwaybetwee'n the lower edge of the face lb and the recess 13 (Fig. 1), and the receptacle is then considered to be set for action. At this moment the set-screw 12 isloosened to allow the spring 10 to act the moment the steamer trigger 6 is released by the passage of the roller 7 off the edge of the standard against which it bears, said release causin the stem to be forced either over the face or into the recess 13 de ending in which direction the'receptacle ms tilted. The moment the receptacle'has been balanced, the attendant starts the vacuum-pump or exhauster P, thereby abstraetin the air from the receptacle (or rarefyin'i 1e atmosphere within it) and then inline 1 ing the latch-bolts 20 from the lid: The lid atelv unfastenbolts, but by atmospheric pressure alone. ll .the body m the receptacle has life m it, M will rebel against the vacuum (or partial vacuum) with which it is now urrounded, and give a spasn'iodic (muscular) movement, which movement will destroy the equilibrium of the receptacle and body, causing the receptacle to tilt in one direction or the other. about its knife-edge trunnions'3. Should the head of the receptacle drop or tilt down, the roller 7 will ride oti' the edge. of the standard 1, the spring 10 forcing the stem 0 into the groove or recess 1?), and

drawing the valve 8 with it so as to uncover the port in the ring 9 (Figs. (3, 7), the pond cut '25 dropping against the bearing 26 so as to prevent any accidental return of the receptacle to its original position. The opening of the valve 8 allowsan in'rush of air into the receptacle through the port in the bushing 9, thus restoring the necessary onygen to the respiratory organs of the body in the receptacle. The inrushing air too, restores the atmospheric pressure within the receptacle, thus allowing the flexed springs 52% to act on the lid L and raise it to give the resuscitated person plenty of air. Should any spasmodic or muscular movement of the apparently lifeless person happen to tilt the receptacle in the opposite direction, that is, to depress the foot of the receptacle, the roller 8 will pass off the standard 1 and over the race I) (Fi 5), thus again uncovering the port in the ushing 9 and allowing an inrush of. air into the partiallyexhausted chamber of the receptacle. The muscular movements of the body by which the equilibrium of the rccep tacle is destroyed are due to the unnatural environment brought about by the vacuum in the receptacle, against which environmentthe body rebels. A slight movement of course, destroys the equilibrium of the receptacle, and hence the valve-stem or trigger 6 responds instantly.

The production of a. partial vacuum in the receptacle holding the body is of course but one method of abstracting the. oxygen from the receptacle containing the body,-

snch abstraction being the equivalent of rarefying the air (the nitrogen being abstracted simultaneously by the cxhauster or pump). Any other method (such as a chemical proccsslof destroying the oxygen within the receptacle so that the body may be convulsively or muscularly atl'ccted is within the contemplation of my invention,

since it is the abstraction of oxygen which is primarily depended on to produce the result here sought.

The automatic action of the apparatus need not be depended on, for the attendant watching the body, may, the moment he observes signs of life therein, simply open an air-cock or valve V of any ordinary type,

and allow an inrush of air into the receptacle. The autonuu-ic action however may be used whereno attendant may be present.

Having described my invention, what I claim is:- Y

F2. in a'resuscitating apparatus, a rece taclc for the deposit of an apparently li eless body, in combination with means for abstracting air from the receptacle, and means for readmitting a proper complement of air to the respiratory organs of the person in the receptacle, upon the body showing signs of life. i

3. In a resuscitating apparatus, a suitable movably' mounted receptacle having inclosing walls, and provided with .means for exhausting the air from within the receptacle, the receptacle wall having an'inlet port, a

valve' normally coveringv said port, and' means for openin said valve and uncovering said port wit 1- a movement of the receptacle from a predetermined position.

4. In a resuscitating apparatus, a suitable tilting receptacle, mounted to oscillate about a substantlally central axis, and rovided with means for exhausting the air. therefrom, an air inlet port being formed in one of the walls of said receptacle, a spring-controlled valve movable across said port, a stem for the valve, a member for engaging one end of the stem and arresting movement thereof to maintain the valve in position over the port, and suitable formations on said member to allow for the release of the stem with any oscillation of the receptacle whereby the port is uncovered and a" admitted to the receptacle.

5. A resuscitating apparatus comprising a vertically oscillating receptacle. balanced upon the deposit of the body therein, and suspended about a substantially central transverse axis, a fixed standard positioned in front of one of the terminal walls of I:

the receptacle, said wall being provided with an air inlet port, a spring-controlled valve movable across the port, a stem for the valve moving in a line transverse to the standard, a roller on the stem engaging the 'standa rd and forced against the same by the expanding action of the spring, the standard having a recess or a portion removed from the body thereof. in the path of travel of the roller whereby with a given oscillation of the receptacle the roller end of the stem is brought opposite said recess or beyond the end of the standard, and the stem moved under the action of the spring and the port aforesaid is uncovered, and means for ex- I hausting the air from the receptacle whereby a movement in the body deposited therein takes place,'.and the necessary oscillation is imparted to the receptacle, for the purpose set forth.

8. -In the-resuscitation of persons apparently lifeless, the method of depositing the person in a receptacle, and abstracting there-. from suitable portions of oxygen whereby the ir within the receptacle and about the hea and chest of the person is rarefied, and

admitting a proper complement of oxygen into-the receptacle and to the resplratory organs of the body with any indications of life therein.

9. In the resuscitation of persons apparently lifeless, the method of placing the body in a receptacle and producing a partial vacuum in the same, and admitting a proper complement of air into the receptacle to the respiratory organs of the body with any indications of life therein.

10. In the resuscitation of persons apparently lifeless, the method of exposing the respiratory organs and mouth of the person while in a reclining position to a gas deficient in oxygen, whereby muscular move-' ment in the body of such person results,

then supplying a proper .quantitv of oxygen to said organs, upon detection of such movement.

In testimony whereof I afiix my signature, in presence of two witnesses.
